struct
Acts::InterpolatedBFieldMap
::
FieldCell
¶ struct representing smallest grid unit in magnetic field grid
This type encapsulate all required information to perform linear interpolation of magnetic field values within a confined 3D volume.
Public Functions
-
FieldCell
(std::array<double, DIM_POS> lowerLeft, std::array<double, DIM_POS> upperRight, std::array<Vector3, N> fieldValues)¶ default constructor
- Parameters
[in] lowerLeft
: generalized lower-left corner of hyper box (containing the minima of the hyper box along each Dimension)[in] upperRight
: generalized upper-right corner of hyper box (containing the maxima of the hyper box along each Dimension)[in] fieldValues
: field values at the hyper box corners sorted in the canonical order defined in Acts::interpolate
-
Vector3
getField
(const ActsVector<DIM_POS> &position) const¶ retrieve field at given position
- Return
magnetic field value at the given position
- Pre
The given
position
must lie within the current field cell.- Parameters
[in] position
: global 3D position
-
bool
isInside
(const ActsVector<DIM_POS> &position) const¶ check whether given 3D position is inside this field cell
- Return
true
if position is inside the current field cell, otherwisefalse
- Parameters
[in] position
: global 3D position
Public Static Attributes
-
constexpr unsigned int
N
= 1 << DIM_POS¶ number of corner points defining the confining hyper-box
